Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage detection, in particular to a leakage detection device for urban water supply pipelines. Background Technique

[0002] At present, the urban water supply in China mainly relies on water supply pipelines. Therefore, it is crucial to detect the water supply pipelines to ensure their normal operation. The water supply pipelines are severely aged due to long-term over-limit operation and disrepair, and are prone to leakage, or leakage occurs due to factors such as corrosion and man-made damage. This not only causes waste of water resources, but also has an adverse impact on the environment and road safety around the water supply pipelines. Therefore, the leakage detection of water supply pipelines is an important content.

[0003] In the prior art, generally, pipeline CCTV detection technology is used to detect the leakage of the pipeline network. It mainly detects the leakage situation in the pipeline by commanding the camera robot to automatically move through the pipeline, so as to ensure the smoothness and safety of the urban drainage system. However, the camera robot can only crawl inside the horizontally arranged pipeline, and when the pipeline is vertically arranged, it cannot perform the detection work. Therefore, it is necessary to propose a leakage detection device for urban water supply pipelines to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a leakage detection device for urban water supply pipelines, which has the characteristics of being convenient for detecting the leakage of both horizontally and vertically arranged pipelines.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A leakage detection device for urban water supply pipelines, including a camera robot and two support frames. On the opposite sides of the two support frames, vertical plates are fixedly connected. A winding shaft is rotatably connected between the two vertical plates, and a rope is fixedly connected to the outer wall of the winding shaft;

[0006] A driving mechanism is arranged on the right side of the winding shaft;

[0007] The other end of the rope is fixedly connected to a holding seat. A connecting disk is installed on the upper side of the camera robot. An internally threaded cylinder is rotatably connected to the upper end of the connecting disk. The lower end of the holding seat is fixedly connected to a screw rod that is threadedly connected to the inner wall of the internally threaded cylinder.

[0008] In order to facilitate the rotation of the winding shaft, as a preferred leakage detection device for urban water supply pipelines of the utility model, the driving mechanism includes a connecting shaft fixedly connected to the right end of the winding shaft and penetrating through the right vertical plate. A worm gear is fixedly connected to the right end of the connecting shaft. A driving frame is installed at the right end of the right vertical plate. A worm that meshes with the worm gear is rotatably connected between the front and rear sides of the inner wall of the driving frame, and the worm is driven by a motor installed on the front side of the driving frame.

[0009] To improve the stability of the device during use, as an optimization of the urban water supply pipe network leakage detection device of the present utility model, fixed plates are fixedly connected to both the left and right sides of the support frame. A plurality of through holes are penetrated through the outer walls of the two fixed plates, and fixing nails are arranged inside the plurality of through holes.

[0010] To facilitate restricting the winding position of the rope during winding, thereby avoiding the rope from being too scattered after winding, as an optimization of the urban water supply pipe network leakage detection device of the present utility model, two limiting rings are installed on the outer wall of the winding shaft.

[0011] To facilitate improving the anti-slip effect when rotating the internal thread cylinder, as an optimization of the urban water supply pipe network leakage detection device of the present utility model, anti-slip patterns are provided on the outer wall of the internal thread cylinder.

[0012] To facilitate winding the rope, as an optimization of the urban water supply pipe network leakage detection device of the present utility model, the rope is made of a flexible material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By commanding the camera robot to automatically travel inside the horizontally arranged pipeline, the leakage situation inside the horizontal pipeline can be detected. When it is necessary to detect the leakage of the vertical pipeline, the screw is screwed into the inside of the internal thread cylinder, thereby completing the installation of the camera robot. Then, the camera robot enters the inside of the vertical pipeline and is supported by the ground through two support frames. Then, the rope is gradually unwound by rotating the winding shaft. At the same time, the camera robot gradually extends into the inside of the vertical pipeline, and the leakage situation inside the vertical pipeline is detected by the camera robot. Furthermore, through this method, the effect of facilitating the leakage detection of both horizontally and vertically arranged pipelines is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

When it is necessary to detect the leakage of the vertical pipeline, by rotating the internal thread cylinder 2 and keeping the holding seat 4 stationary, the screw rod 3 can be screwed into the internal thread cylinder 2, thereby completing the fixation of the holding seat 4 and the internal thread cylinder 2, and at the same time completing the installation of the camera robot 1. Then, the camera robot 1 enters the inside of the vertical pipeline and is supported by the ground through the two support frames 13. Then, the driving mechanism drives the winding shaft 7 to rotate, and the rope 5 can be gradually unreeled. At the same time, due to the action of gravity, the camera robot 1 will gradually extend into the vertical pipeline, and the leakage situation inside the vertical pipeline can be detected by the camera robot 1. Through this method, the effect of facilitating the leakage detection of both horizontally and vertically arranged pipelines can be achieved.

[0024] As a technical optimization solution of the present utility model, the driving mechanism includes a connecting shaft 8 fixedly connected to the right end of the winding shaft 7 and penetrating through the right vertical plate 6.

[0025] In this embodiment: The motor 12 drives the worm 10 to rotate, and then drives the worm gear 9 and the connecting shaft 8 to rotate, so as to achieve the purpose of facilitating the rotation of the winding shaft 7.

[0026] As a technical optimization solution of the present utility model, fixing plates 14 are fixedly connected to both the left and right sides of the support frame 13. A plurality of through holes 15 are penetrated and opened on the outer walls of the two fixing plates 14, and fixing nails 16 are arranged inside the plurality of through holes 15.

[0027] In this embodiment: By inserting the plurality of fixing nails 16 into the plurality of through holes 15 and driving them into the ground, the stability of the device during use can be improved.

[0028] As a technical optimization solution of the present utility model, two limiting rings 17 are installed on the outer wall of the winding shaft 7.

[0034] Working principle: During use, first, the command camera robot 1 automatically travels through the horizontally arranged pipeline, so as to detect the leakage situation in the horizontal pipeline. When it is necessary to detect the leakage of the vertical pipeline, by rotating the internal thread cylinder 2 and keeping the holding seat 4 stationary, the screw 3 can be screwed into the internal thread cylinder 2, thereby completing the fixation of the holding seat 4 and the internal thread cylinder 2, and at the same time completing the installation of the camera robot 1. Then, the camera robot 1 is made to enter the internal part of the vertical pipeline and is supported by the ground through the two support frames 13. Next, the plurality of fixing nails 16 are inserted into the plurality of through holes 15 and driven into the ground, thereby improving the stability of the device during use. Then, the motor 12 drives the worm 10 to rotate, thereby driving the worm gear 9 and the connecting shaft 8 to rotate, and then driving the driving winding shaft 7 to rotate, and then the rope 5 can be gradually unwound. At the same time, due to the action of gravity, the camera robot 1 will gradually extend into the internal part of the vertical pipeline, and the leakage situation inside the vertical pipeline is detected by the camera robot 1. Through this method, the effect of facilitating the leakage detection of both horizontally and vertically arranged pipelines can be achieved.
